A 32-year-old multiparous woman (G3P2) at 34 weeks of gestation presents to the emergency department with painless vaginal bleeding of 200 mL. She denies abdominal pain, contractions, or leakage of fluid. Vital signs: BP 128/82 mmHg, HR 92 bpm, RR 18/min. On speculum examination, blood is seen pooling in the vagina; no cervical lesions or polyps are noted. Transabdominal ultrasound shows the placenta covering the internal cervical os completely. The fetal heart rate is 148 bpm with normal variability. What is the most appropriate immediate management?

Explanation

## Clinical Diagnosis **Key Point:** This patient has **total placenta previa** (placenta covering the internal cervical os) presenting with **first episode of painless antepartum hemorrhage (APH)** at 34 weeks in a hemodynamically stable mother with reassuring fetal status. ## Management Principles for Placenta Previa ### Expectant Management (Conservative Approach) For stable patients with previa at <36 weeks: 1. **Hospitalization** — continuous fetal monitoring and readiness for emergency delivery 2. **Pelvic rest** — avoidance of intercourse, douching, and vaginal examinations 3. **Corticosteroids** — betamethasone 12 mg IM × 2 doses (24 hrs apart) for fetal lung maturity 4. **Transfusion capability** — cross-matched blood at bedside 5. **Planned cesarean delivery** — at 38–39 weeks if no further bleeding; earlier if recurrent hemorrhage or labor ### Why NOT Digital Cervical Examination? **Warning:** Digital cervical examination is **absolutely contraindicated** in placenta previa because: - The examining finger may dislodge placental tissue overlying the os - Risk of massive hemorrhage requiring emergency hysterectomy - Only speculum examination is safe for visualization ### Why NOT Immediate Delivery at 34 Weeks? **Clinical Pearl:** In the absence of: - Uncontrolled hemorrhage (>500 mL) - Maternal hemodynamic instability - Fetal distress - Preterm labor ...expectant management is preferred to allow fetal maturation and reduce neonatal morbidity (respiratory distress, intraventricular hemorrhage, necrotizing enterocolitis). ## Comparison: Placenta Previa vs. Placental Abruption | Feature | Placenta Previa | Placental Abruption | |---------|-----------------|--------------------| | **Bleeding** | Painless, recurrent | Painful, often concealed | | **Onset** | Usually 2nd/3rd trimester | Any trimester | | **Cervical exam** | **CONTRAINDICATED** | Safe | | **Fetal status** | Often reassuring initially | Often compromised | | **Management** | Expectant (if stable) | Often urgent delivery | | **Delivery route** | Cesarean (absolute) | Vaginal if stable; CS if unstable | **High-Yield:** The **hallmark of placenta previa = painless bleeding + contraindication to digital cervical exam**. ## Rationale for Correct Answer Admission with pelvic rest, corticosteroids, and planned elective cesarean at 39 weeks is the **standard of care** for: - Hemodynamically stable mothers - Reassuring fetal status - Gestational age 34–36 weeks - First episode of bleeding This allows fetal maturation while maintaining maternal and fetal safety.
